Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
Let .
The derivative of sine is cosine:
Then, apply the chain rule. Multiply by :
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: goes to
So, the result is:
The result of the chain rule is:
The result of the chain rule is:
The answer is:
5*cos(5*x) -------------- __________ 2*\/ sin(5*x)
/ 2 \ | __________ cos (5*x) | -25*|2*\/ sin(5*x) + -----------| | 3/2 | \ sin (5*x)/ ---------------------------------- 4
/ 2 \ | 3*cos (5*x)| 125*|2 + -----------|*cos(5*x) | 2 | \ sin (5*x) / ------------------------------ __________ 8*\/ sin(5*x)
